Would you please allow for a month grid display like a regular desk calender so I can look at each weekday as a cube that displays just a sort portion of each of that days event and the start times for either 1 week, 2 weeks or 1 month. (See example) This would make it much easier to see more that just the days of each list and the alarm.

Also the ability to print.

Or maybe find a way to integrate this free calendar format (available in 5 colors) into Rainlendar? Use the the pdf then overlay the data and and display as a pdf in adobe reader?

You can already print the calendar in Rainlendar. There is also possibility to show a day and week views in the latest beta. I can check how much work it would take to make it possible to draw the events directly to the month calendar too.

The problem with the grid calendar is that all the settings will be applied to all the calendars inside the grid so the adjacent days would be shown also in the calendars which are middle of the grid. And I don't think that would work very well.
